M ETALLIC RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 689,704, dated December24, 1901.

' Application filed October 9, 1901. Serial No. 78,031. (No model.)

To aZZ whom it may concern.-

Be it known that I, LUoInN CASTIN, a citizen of the United States ofAmerica, residing at Point Marion, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inMetallic Railroad-Ties,of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inmetallic ties, and has for its object the provision of novel means forconveniently fastening the rails to a tie of this type.

Briefly described, my invention comprises a metallic bar or tie-bodyhaving .on its underneath face a centrally-arranged flange which extendsfrom end to end of the tie. On its upper face the bar or tie-body isprovided with integral clamp-blocks near the ends, these blocks beingadapted to engage the outer face of the rail, the latter being rigidlysecured in position on the tie by means of detachable clamp-blocks,which are fastened to the bar or tie-body. The tie-body intermediate ofthe-rails is preferably made of increased thickness to that at the ends,so as to give rigidity and strength thereto.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout theseveral'views, in which--- Figure 1 is a detail perspective view of myimproved metallic tie with the detachable clamp-blocks removed. Fig. 2is a side elevation of a part of the tie, showing the rail in end viewclamped thereon. Fig. 3 is a detail perspective View of one of theremovable clamp-blocks.

To put my invention into practice, I provide the tie-body or bar, whichmay be com-,

posed of steel, iron, or any other suitable metal, and is preferablyprovided on its underneath face with a downwardly-extending flange 2,which extends the entire length of thetie. This flange 2 permits thetamping of the ties more advantageously than is the case where theentire lower face of the tie is fiush. This tie is provided near eachend with an integral clamp-block 3, which is adapted to embrace theouter face of the rails 4. The inner faces of the rails 4 are engaged ina similar manner by the detachable clampblocks 5, formed substantiallythe same as the integral clamp-blocks 3. These clamp-blocks 5 areprovided with apertures 6, adapted to register with apertures 7 in thetie, and through these registering apertures is passed thesecuring-bolts 8, which are held therein by means of the nuts 9. As theupper face of the clamp-blocks 5 is beveled or at an incline, Ipreferably recess the clamp-blocks, as shown at 10, so as to form aseating-surface for the nuts 9. The tie-body is preferably increased inthickness intermediate of its ends, as shown at 11, which serves to givestrength and rigidity thereto. The rails 4, it will be observed, arefirst placed in position against the clamp-blocks 3, the latter beingrecessed so as to receive the base of the railflange, as shown at 12.The engaging top faces of the clamp-blocks 3 and 5 are beveled toconform to the underneath face of the railtread, and the web engagingface of the clamp-blocks may be constructed to conform to the web of therail.

In the practice of my invention it will be observed that slight changesmaybe made in the details of construction without departing from thegeneral spirit of the invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I A metallic tie which comprises in itsentirety a body portion having an enlarged central portion and having asingle flange on its under face extending longitudinally of the same, anintegral clamp-block on one end of said body portion engaging therail-base, rail web and under face of the rail-head, and a removableclamp -block engaging the railbase, rail-web and under face of therail-head and seated on the upper face of the body portion adjacent tosaid enlarged portion, seats on said removable clamp-block, and boltsextending through said removable clamp-block and body portion, andengaged by nuts seated in said seats, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
